Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wireless remote control device used in, for example, video systems, TV C217 equipment, audio equipment, and the like.

For example, in wireless remote control devices such as audio equipment, the main device such as an F-layer, etc., and the main device are separated from each other, so the operator can operate switches on the main device, operate the frame, etc. In this case, it consists of a small remote control (hereinafter referred to as remote control) device. As a transmission medium from the remote control device to the main device, for example, infrared ultrasonic waves are used.

In such a wireless remote control device, it is important to check whether the control signal is being transmitted from the remote control device in the operator's hand, and whether it is being received by the main device without being interrupted due to interference with the transmission path. It is inconvenient not to be able to confirm whether Furthermore, even when remote control is performed over a wired transmission line, the chances of the transmission line being interrupted by interference are extremely rare compared to wireless control, but transmission and reception can be confirmed. It is convenient to do so.

Therefore, conventionally, this type of remoteco i operation device is provided with a display element such as an LED to indicate whether or not a control signal is being transmitted, or a display device is provided in the main device to indicate whether the control signal is being received. No, a means is used to indicate whether it is inside or not.
